MSNBC Host Campaigns in Wisc.

MSNBC host Ed Schultz will discard media punditry for outright campaigning when he joins DNC Chairwoman Debbie Wasserman Schultz to support the recall of Wisconsin Gov. Scott Walker.

Schultz has made the Wisconsin recall election a big topic on his MSNBC program. His appearance at the state Democratic convention will come a few days after the recall election takes place.

Cable news hosts routinely have public speaking engagements, although engagements closely associated with political parties or politicians are often considered uncouth, even for opinion hosts. MSNBC suspended Keith Olbermann and Joe Scarborough in late 2010 for donating money to a handful of congressional hopefuls.

Schultz’s speech is part of the effort to help  Milwaukee mayor Tom Barrett close a 7-point poll deficit.
